Copper has a higher activity than hydrogen and cannot replace it.
Copper has a lower activity than hydrogen and cannot replace it.
The reaction cannot occur because water is a reactant.
answer is Copper has a lower activity than hydrogen and cannot replace it.
Answer: Option (c) is the correct answer.
Explanation:
It is known that a stronger element is able to displace a less stronger element in a chemical reaction.
And, according to the reactivity chart hydrogen is more reactive in nature than copper.
Therefore, when Cu is added to then there will be no reaction because copper is less reactive than hydrogen.
Thus, we can conclude that the reaction not proceed to a product because copper has a lower activity than hydrogen and cannot replace it.

what is the mass of a ball whose density is 0.250 g/cm3 and whose is 200 cm3
Answer : The density of book is
The mass of a ball is, 50 grams.
Explanation :
Part 1 :
Density : It is defined as the mass contained per unit volume.
Formula used :
Given :
Mass = 1800 g
Volume =
Now put all the given values in the above formula, we get :
Therefore, the density of book is
Part 2 :
Formula used :
Given :
Volume =
Density =
Now put all the given values in the above formula, we get :
Therefore, the mass of a ball is 50 grams.
Answer: For your first question about the book, the answer is 6 g/cm^3. For the ball, your mass is 50 grams.
Explanation: density = mass/volume; for example: your book was 1,800 g. Divide that by 300 cm^3 to get 6g/cm^3. For the ball, mass = density*volume, so you need to multiply .250 by 200 cm^3
